One possible consequence could be Percy feeling betrayed and heartbroken. His trust in Annabeth would be shattered, and he might become withdrawn or angry.
Percy could also be the type to demand an explanation from Annabeth. He wouldn't just let it go without trying to understand why she did it. He's not a pushover, and his relationship with Annabeth was important to him, so he would want to know what led to this betrayal.
One idea could be that Percy and Annabeth are new students at a high school filled with mythological secrets. They have to hide their demigod status while also dealing with normal high school problems like exams and bullies. Maybe they join the school's swim team and debate club respectively, which could lead to some interesting interactions.
Well, it's possible that such a fanfiction exists given the creativity of fanfiction authors. They like to experiment with different relationship dynamics. But considering the popularity and the nature of Annabeth and Percy's relationship in the source material, this would be quite a shocker. It could also attract a lot of criticism from fans who are attached to the original relationship, while others might be interested in seeing how such a different plot would unfold.
There might be such fanfiction out there in the vast world of fan - created content. However, this kind of plot goes against the original relationship dynamics in many fans' eyes. It's important to note that fanfiction can cover a wide range of scenarios, some of which may be controversial or not in line with the general perception of the original story.
In most fanfics, this is often just a fictional and sometimes out - of - character plot device. There's no real evidence within the official Percy Jackson canon for such a thing, but in fan - created stories, it could be based on the author's desire to create drama. However, it goes against the core relationship we know from the original books.
One idea could be that they compete in various school competitions like academic decathlon or sports events, always trying to outdo each other. For example, in a science fair, Percy might do a project on underwater ecosystems because of his love for the water, while Annabeth does something related to architecture. Their rivalry makes them both push harder and come up with more creative ideas.
They could be involved in a high school project that turns out to be related to an ancient prophecy. Percy might use his water - controlling abilities in a science experiment in a really cool and unexpected way, and Annabeth would be there to explain the historical context behind it all.
There's Tyson, Percy's cyclops half - brother. In high school fanfiction, he can be really endearing as the big, strong but gentle guy. He might be on the school football team or something similar. And then there's Rachel Elizabeth Dare. She could be the artsy girl in school who has a bit of a crush on Percy and causes some jealousy with Annabeth, adding some romantic tension to the story.
One possible fanfic could be about Percy and Annabeth facing a new mystery in high school. Maybe there's a strange teacher who seems to know more about their demigod past than they're comfortable with. Percy could be struggling with his ADHD in the academic setting, and Annabeth is constantly helping him study while also trying to solve the mystery of the teacher.
